wifi: iwlwifi: mvm: add support for the new STA related commands

As a part of the new MLD FW API changes, we have new commands for STA
related operations (add/remove/aux/disable tx).
Add structures and enum definitions, along with part of the functions
that sends this commands.
This functions will be in used and more will be added in the next patches.
